Statistically significant findings may be clinically irrelevant…

Very interesting blog post on the necessary skepticism with which any results should be  approached:

“A statistically valid association, though, is not necessarily significant in the sense of ‘important’. A sliver of a difference could reach statistical significance if a study is big enough. For example, if one group of people sleeps a tiny bit longer on average a night than another group of people, that could be statistically significant. But it wouldn’t be enough for one group of people to feel more rested than the other.”

Go read  the whole thing. It’s short. 🙂
